The plan is not justified as the exceptional circumstances for removal of Green Belt around Knebworth (sites KB1,2,4). These sites provide a significant contribution to maintaining the spacial strategy between Stevenage, the villages and Welwyn Garden City along the B197. The identify of Knebworth is under threat from co-existence with Stevenage and Woolmer Green. NHDC does not appears to have co-operated with Welwyn Hatfield Borough Council on their submitted Local Plan as the impact of site HS15 (150 homes) on the boundary with Knebworth has not been considered in the assessments for Knebworth.
